I am unable to start any of my VMs interactively. They work when run headless however (--type vrdp)
If I try to run normally I get:
$ VBoxManage startvm Kubuntu Waiting for the VM to power on... VBoxManage: error: The virtual machine 'Kubuntu' has terminated unexpectedly during startup because of signal 6 VBoxManage: error: Details: code NS_ERROR_FAILURE (0x80004005), component Machine, interface IMachine, callee
My host machine is an Intel iMac running 10.6.7, and I'm using VirtualBox 4.0.6 with the Oracle extensions installed.
Further info: The virtual machines start up just fine interactively if I use sudo. That seems to imply there is some sort of bad permission or locked file or something somewhere, but I have already checked all the files in Library/VirtualBox.
